Abstract

Abstract: The use of anchors in construction is gaining popularity to connect steel and concrete constructions, and to transmit tensile loads acting onto the concrete. This research aims to find out the difference in the strength of anchor based on two methods of installations that are cast in place compared to post installed with the influence of effective depth, diameter of anchor and quality of concrete, and failure of concrete breakout. Expansion anchor used in this study is "Sanko" M12x100 and ready-mix concrete PT Bonindo Ungaran, fc 25 MPa with 6 pieces of test specimens of 300x300x150 mm. Each specimen has 4 anchors with a distance between the anchors of 100 cm, the distance between the anchors to the edge of the concrete 100 mm, and the depth of installation (hef) of 60 mm. The result of the study is the predicted value of the anchor pullout capacity with the failure of concrete breakout due to the theoretical pullout, namely 42,223 N, anchor pullout test results with cast in place method of 40,574 N and post installed method by 37,494 N. Tensile strength tests (material) of anchor (fy) 338 MPa, for flat concrete compressive strength strength of (f’c) 25,698 MPa. The results of the cast in place pullout test are larger and better than post installed (40574 N37494 N). Failure that occurred in cast in place method is a failure of concrete breakout and post installed method has occurred slip. Failures that occur are relevant to the theory.

Abstract

Abstract. The Sampean Baru watershed is categorized as an area with a very high level of vulnerability to drought. The purpose of this study was to assess the hydrological drought in the Sampean Baru watershed. NCEP / NCAR Reanalysis climate change data is used to obtain synthetic rainfall models of the past. This climate change data has crude resolution and is global in scale. The NCEP / NCAR Reanalysis data was processed through a downscaling process to obtain local scale climate data in the form of past synthetic rains. Artificial Neural Network (ANN) is one of the downscaling models used in this study. The ANN downscaling output was processed through discharge modeling using SWAT. Hydrological drought assessment used the Standardized Precipitation Index (SRI) method. The SRI calculation was based on the accumulated discharge over a period of time. The results indicated that the ANN downscaling process can bridge global scale climate data to local scale climate data. SWAT modeling gave excellent results. SRI-6 can describe past droughts. It can be seen from the compatibility between the results of the drought assessment and the drought data belonging to the relevant authorities.

Abstract

Abstract Fire is a disaster that must be avoided in various ways, one of them is by using a fire extinguishing system to prevent fire disaster. This study used the Semarang City Health Office (DKK) Building as a sample. The purposes of this research were; (1) to find out whether the application of the fire protection system at DKK Building has met the regulations and (2) to determine whether the water distribution in the fire protection system in the Semarang DKK Building is functioning properly as needed. Data collection methods in this study consisted of observation and literature study. The observation was used to find research data in the form of planning drawings on the building protection system and the literature study was carried out to obtain data in the form of standard tool specifications and rules for using tools in the protection system. This study also used an analysis method based on an application program called Epanet 2.0. The Epanet program was used to simulate a hydraulic model according to the fire protection system at DKK Building. The results of the analysis using the Epanet 2.0 show that the sprinkler system has met the needs based on the amount of water supply discharge and based on the required pressure. The underground tank volume of 150 m3 has met the requirements based on SNI 03-3989-2000. The pressure value for all sprinklers has met the requirements of SNI 03-3989-2000 with the smallest pressure value is 2.5 kgf / cm2. The sprinkler system does not meet the water distribution value set in NFPA 13 with a maximum distribution time of 50 seconds while the analysis results show that the distribution time is 205 seconds. The pressure value at all points of the fire hydrant system meets the SNI 03-1745-2000 rules with a maximum value not exceeding 24.1 bars. The pressure value at the farthest hydrant box hose connection does not meet the SNI 03-1745-2000 rules with the pressure value at the farthest hydrant box is 4.6 bars, where is the minimum pressure is 6.9 bars.

Abstract

Abstract: Anchor serves to connect steel and concrete construction that can transfer steel pull-out load to concrete. Sanko hammer drive anchor usually has been available in the model of expansion that can be installed into concrete with cast in place and post installed methods. The experiment was aimed at comparing pull out failures of Sanko hammer drive expansion anchor using cast in place and post installed installation methods based on pull-out failure behavior. Experimental data were obtained from the pull-out strength test of Sanko hammer drive expansion anchor, compressive strength test and ready-mix concrete split tensile test, adhesion strength test and group anchor pull-out test which consists of four units of anchor with diameter of 10 mm planted 90 mm depth on T concrete beams with dimension of 300 mm x 300 mm x 150 mm as many as three beams for each of them using cast in place and post installed installation methods. The results of the experiment showed that concrete compressive tension value (f’c) is 25.69 MPa, anchor tension value (fu) is 383.25 MPa, anchor adhesion tension value (μ) with cast in place method is 2.25 MPa and post installed method is 1.56 MPa. Theoretically, the damage occurred in pull-out condition; while in the experiment, the test showed a difference in pull-out capacity using cast in place installation method of 38.38 kN with deformation of 13.81 mm, which is higher than theoretical value of 26,083 kN and using post installed method of 36.62 kN with deformation of 8.89 mm, which is higher than theoretical value of 18,084 kN and the experiment indicates that the anchor is perfectly pull-out.
